UNITED STATS LEONARD CONOW, or CORTE MADEIRA, CALIFORNIA, essronon T0 SAN FRANCISCO, CALIFORNIA;

. OIL BURNER.

Application filed November 26, 1920. Serial No. 426,372.

To all whom it may concern.

Be it known that I, LEONARD CoNoW, a citizen, of the, United States, residing at Corte Madera, in the county of Marin and State of California, have invented new and useful Improvements in Oil Burners, .of which the following is a specification.

The present inventionhas special reference to an improved oil burner especially designedforuse in coal or wood cookstoves and particularly adapted for burning the lighter variety of oil, such as kerosene.

The, primary objectofthe'invention is to provide an oil burner of the character de-' scribed, whichwill be comparatively SIIIlPlG' and inexpensive as to construction; which will be reliable and economical in use; and which maybe easily and, quickly installed in the fire boxbf an ordinary coal and wood cook stove without necessitating any change .in the construction of the stove, whereby said stove may be easily and cheaply converted into the oil burning type.

The invention possesses other advantages and features, some of which, with the foregoing will be set forth at length in the following description wherein I shall outline in full that form of the invention whichI have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit myself to such form since the invention as expressed in the claim may be embodied in a plurality of forms.

Referring to the drawings:

Figure 1 is a fragmentary perspective view of the fire box of an ordinary cook stove, showing the burner of my invention associated therewith, said burner being broken away for the sake of clearness of illustration.

Figure 2 is a longitudinal vertical sectional view through the burner of my invention.

Figure 3 is a transverse sectional view of the burner.

In carrying out one practical embodiment of the invention as shown in the drawings there is provided a cast iron base 1 which is preferably of rectilinear outline and flat, so

that it may be fitted into the firebox 2 of-a cook stove as shown in Figure 1. The base is adapted to rest upon the grating 3 in the 'ing chamber tion 9 is turned so as to extend towards the firebox and practically covers the entire.

floor of said fire box.

on opposite sides of the base, at the centre" thereof is an internally screw threaded open:

ing 5. The "lower end of the'openingis adaptedto receive the fuel feed pipe not.

shown, whereas, the upper. end receives a short upwardly extending pipe. 6. The' pipe ,6 supports and is turnedyintothelower side of a, preferably cylindrical generating for gasifying' chamber 7, said chamber prefer-' ably being of cast iron and havingits flat sides parallel .Wlt-lrtllfi .upperface of .theg';

body. The chamber is relativelyflarge but of considerably. less diameter thanthe width of the base so that said base extends outs alls'i'des of the chamberand wardly from close thereto. 7 p

Extending upwardly fromthe upper side of the chamber 7 is a burner pipe 8 having a downwardly and outwardly curved upper portion 9. The free end of the pipe is closed as at 10 and. at about the middle of the curved portion 9 in the under side thereof is a burner orifice 11, through which fuel issues. This orifice is immediately over the upper flat side of the gasifying or generat 7. Preferably, the curved poroven wall 12 of the fire box. Preferably formed integral with the base 1 on opposite sides of the chamber 7 are upwardly extending air intake tubes 13, the upper endsof which terminate near the upper side of the chamber. These tubes open through the base and permit air, as a supporter of'combustion, to flow from beneath the grating 3 up and around the chamber 7.

In the operation of the burner, fuel is directed into the chamber 7 and after said chamber becomes, filled, the fuel passes up wardly through the burner pipe, escapes through the orifice 11, and drops into the up per side of the said chamber. When the chamber and surrounding portions of the sufliciently to gasify the fuel therein, thefuel is turned on again and fed under pressure to the burner. Any suitable well known means for feeding the fuel under pressure may be used. The fuel now fed under pres sure is forcibly discharged in a gaseous or spray-like form onto the upper side of the chamber and readily ignites as strikes said chamber. The flame is deflected outwardly in a fan-like spread and covers a large area around the chamber so as to keep the chamber properly heated to gasify the fuel in the chamber,

It Will thus be seen that the burner of this invention Will operate econmically and provide an intense effective heat. It desired the burner may be cast in one piece instead of being formed of several parts as shown in the drawings. The base covering the entire grating section 3 acts as a. heat radiating member. By having the burner orifice at about the highest point in the curved portion 9 instead of at the closed end, there is less tendency of clogging at the orifice as the particles of foreign matter in the "fuel will tend to gravitate into the pipe upon either side of the orifice rather than through said orifice. Preferably the chamber '7 is located close to the base so as to provide for compactness and take advantage of the heat radiations from said base.

I claim An oil burner of the character described embodying in its construction a large flat base adapted to rest upon the grating in the fire box of a cool: stove and having an opentake members carried by the plate and eX- tending upwardly from said air intake openi a generating chamber supported by the g nate and in communication With the first n med opening therein and a burner pipe e ending upwardly from the top and near one side of said chamber and being curved outwar lly and downwardly and terminating in closed end spaced Well above and over said generating olntmber said pipe being closed at its upper end and provided With an outlet orifice located immediately above and over said chamber, at a point spaced from said closed end, said orifice being located at the highest point in the curved portion of the pipe to prevent particles of foreign matter from clo 'ing the orifice.
